"Spirally" Examples

Spiral

Nested loops or recursive functions

Example 1: Printing a spiral

python
def print_spiral(n):
turn 0
for i in range(n):
for j in range(n):
if (turn % 2 0 and i < j) or (turn % 2 1 and i + j > n - 1):
print("", end" ")
else:
print(" ", end" ")
turn + 1
print()

print_spiral(5)

Geometry

Example 2: Calculate area of a spiral

python
import math

def spiral_area(n):
return n2 math.pi

print(spiral_area(10))

Computer Science

Example 3: Searching in a 2D array

python
def search_spiral(matrix, target):
rows, cols len(matrix), len(matrix[0])
row, col 0, 0
directions [(0, 1), (1, 0), (0, -1), (-1, 0)]

right, down, left, up

dir_index 0

while row < rows and col < cols:
if matrix[row][col] target:
return True
matrix[row][col] + 1

mark as visited

nextrow, nextcol row + directions[dirindex][0], col + directions[dirindex][0]
if 0 < nextrow < rows and 0 < nextcol < cols and matrix[nextrow][nextcol] ! 0:
row, col nextrow, nextcol
else:
dirindex (dirindex + 1) % 4
row, col row + directions[dirindex][0], col + directions[dirindex][0]

return False
